Most HDTV sets come with built in freeview. The full benefit of HD is only apparent if you play HD games, HD DVD's (on an HD DVD player) or receive an HD broadcast. You can do this with Sky or for free (almost) if you install Freesat (no subscription just a box and sat dish). Definitely worth getting an HDTV if you're buying a new TV. I'd recommend this one, comes with a free Bluray player unless you're using a noisy PS3.
